The invention relates to headlights, as de scribed in the present specification and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially of the novel features of construction pointed out in the claims for novelty following a description containing an explanation in detail of an acceptable form of the invention.

The objects of the invention are to e iminate the dangers incident to the glaring eifect of the headlight of the approaching vehicle, which as is Well known produce a blinding effect on the drivers, so much so as to cut out their vision in front for a good distance before and after passing the other Vehicle; to insure good projection in the dipped positions of the headlights fully one half the distance of the regular projection of the light, thereby insuring a good driving light even when thrown downwardly and generally to provide a durable and serviceable mechanism for dipping headlights.

In the drawings, Figure 1 is a vertical sectional view of the reflector and its operating parts.

Figure 2 is a rear elevational view of the operating mechanism.

Figure 3 is a perspective detail of the lifting links, levers and rests.

Figure 4 is a side elevational detail of the lifting mechanism in its upper position.

Figure 5 is a side elevational view of the front portion of a motor car, showing the application of this invention thereto, and the headlight in its normal driving position.

Figure 6 is a side elevational view of the front portion of a motor car, showing the headlight in its dipped position.

Like numerals of reference indicate corresponding parts in the various figures.

Referring to the drawings, the reflector indicated by the numeral 10 is rigidly secured to a sleeve 11 and to the trunnions 12 and 13 at either side of said sleeve, and projecting into the pivot bearings 14 and 15 secured to the frame 16.

The ,frame 16 is preferably of circular form, though not necessarily so, and may be made with the bridge 17, elevated in the HEADLIGHT 1528. Serial No. 288,216.

central portion 18 and carrying on the said elevated portion the solenoid coil 19 and the terminals 20 and 21 of said solenoid.

The core 22 of the solenoid extends downwardly and is a gravity operated core having the slot 23 at its lower end, in which the yoke 24% and particularly the lug 25 is pivotally held by the pivot 26.

Th bracket 27 is secured to the bottom of the frame and is formed with the upright 9 at its front side reaching towards the centre. the upright 29 carrying the stop 30, which is formed of rubber inserted in the socket 31.

The toggles 32 and 33 form the toggle joint 3i, and these toggles are in plate form, the toggle 33 being pivotally secured intermediate of its length by the pivot pin to the lower end of the yoke 24, while the same toggle 33 at its rear end is secured to the upright 28, by the pivot pin 36.

The other toggle 32 is secured to the refiector 10 below the sleeve 11 by the pivot pin 37, this pivot connection of the toggle 32 to the reflector being in the normal position of the lamp above the toggle joint 34;, therefore any downward pressure on the reflector which would tend to dip it, is met by the joint 3 1, that is to say, the said toggle joint remains on the lower side of the centre between the pivot connections 35 and 37, thereby securely locking the reflector to its best driving position, so long as the solenoid coil remains de-energized The electric lamp socket 38 containing the electric lamp 39 is slidably mounted in the sleeve 11 and adjusted for focusing purposes by the screw 40 inserted through the lug 41 from said socket and through the lug 42 from said sleeve, thereby moving it forwardly and rearwardly until the proper focus is obtained, of course there is no real novelty about the focusing of the lamp but in the present instance it is done entirely from the inside instead of from the outside.

The wire connections 43 and 44 are from the lamp socket 38 and from the terminal 21, and are joined in the armored cable 45, the other terminal 20 is connected to the ground by the connector 46.
